It's Suzuki M15A, yes it has VVT on intake cam only. Currently we have old Nissan T28 from Silvia S15 but it spools too late, 4700 rpm or so. Looking for something to be on boost by 4000 for the latest but still give us some power potential on the top end
@@IggySport1388 yeah a t28 especially an older variant will be way too big. The 22-300 or even the 17-250 might be ideal depending for what power you are aiming for The 300 on this engine should definetly hit full boost below 3500 You can improve spool by advancing the vvt angle to the maximum before the turbo hits full boost this can help a lot and improve spool by up to 500 rpm
I think I will go with the pulsar in this video. I also see the pulsar is ball bearing while the original Garret is journal. I hope the stock M15A can tolerate the spool coming on earlier 😅😅
I installed in my car a Td04HL-20T with a 0.61 a/r and I am very satisfied with it. Fast response and a lot of power. It's not that the GBC and their copies are bad turbochargers. It's that Garrett came in this market 20 years later.
The problem with the 20g turbos is that the response is much worse. When youve tried a gbc you know what i mean. The 20g arent bad but jist a lot slower spoolibg than the gbc ones
I sent an email to Pulsar inquiring about not having the 3942 on the site, follow the answer "We had some tech issues with the 3942C, currently it's unavailable, we do not have an ETA yet."
I have a Lotus Esprit 3.5 liter V8 twin turbo that i was thinking about replacing the t25 turbos on. I am only shooting for 500 crank hp, which would be better, GBC20-300 or GBC22-350?
id say in that case the 20-300 would be enough, if you want a bit more headroom, choose the 350. though that will probably hit full boost about 300-400 RPM later id guess. on a 1.6 wich would be a bit smaller than half of yours the 350 will hit full boost (in that case 15 psi) at about 3800
@@throttlebuddies0 the tune i will be running is a 1 bar tune, and stock boost on the car with the t25 turbos pushes 11psi. Is 1bar too much for the 20-300 turbo? From my little knowledge of compressor maps, it appears the 22-300 is most efficient at 1 bar of boost
@@260sxse the stock wastegate actuator will do about 1 bar. thats true these turbos feel right at home at about that pressure, though they can also handle a bit more depending on circumstances. for exmaple a lower compression engine might need a bit more boost to reach the same power levels.
@@throttlebuddies0 i appreciate all the info! I think the 22-300 will be the perfect slight upgrade over stock. The Lotus V8 is only 8:1 compression ratio so very low indeed. I am still on stock internals so cant really push it much more than the 1 bar (and still need luck at that lol)
@@260sxse sounds good, but if you buy an original garrett watch out, as the "0.5 bar" actuators, actually open up at 1 bar so id suggest getting a different one or one with the option of swapping the springs. had that issue with two GBC units not, and can be a problem for engines with stock rods
Hi, thanks for this video! I'm looking for upgrade my K04-023 on 1.8T. Do you have some experience with GBC22-350 on 1.8T 20V engine? I would like to know what RPM the turbo spools to 1b and peak power/tq :)
I know that the 2871 hits full boost at around 4300 The gbc 350 is going to be able to hit boost at around 3000-3300 I suppose since the new aerodynamics of the turbine improve response by a lot
Thank you for sharing it! I'm from Brazil and I'm researching about GBC series. I saw in another video that a GBC 20-300 is more effective than a GT2554R! Journal Bearing turbo more efficient than a ceramic bearing turbo?
Moin, sag mal ist das immer noch aktuell? Hab n audi A4 B7 mit dem BFB und möchte in der Zukunft auch bissi was rausholen, aber bin da noch nicht so drin in der Materie :D
I'm running one of them atm(Garrett), do you think we need an oil-cooler set up? I got boost creep up to 12-13psi with a 7psi spring.... Buuutt it's super fun going into boost at 2.1k rpm give or take
Well were running 8-10 psi on a 1.6 which doesnt even have a oil water heat exchanger and not running an oil coole Although a 71 degree thermostat, reroute and big radiator is highly advisable
well it appears that the 0.5 bar actuator acts more like a 14 psi or 1 bar actuator so in theory you could say that it was but not really in the sense that its "overboosting" and rather that the actuator just works at a different pressure than advertised.
@@throttlebuddies0 yes that is true. I have 3 actuators. The original says 0.5 (opens at ~1.2 bars).second opens at 0.5 till 1.4 still causing over boost. Third is forge actuator 480009 softest spring cracks at 0.35 -0.7 bars (green spring), the third actuator will arrive on friday 🥲 if the overboost problem still persists i will need to port the wastegate 🥲and hopefully no other problems
@@user-lj8bt9hc8t yes should be enough space its only at the top where the windows meets the firewall on the beetle where there is less space. with a low mount you should be fine even with a gt30 in theory. i think the GBC 22-350 or the GTX2860 Gen 2 from pulsar should be your best options
disco potato gt28....is the best turbo for the 1.8t 20v. will need rods and valves but 360whp is actually possible with ease. nice amount of lag if your into these things. once on boost....as you would expect.... mental
the old gt28 is outdated by now... you either go for a gtx 2860 Gen 2 which will be able to handle 400 whp whith earlier spool than the old 28 or go for the gbc 22-350 wich will be enough for 320 WHP at way way earlier spool
@@throttlebuddies0 noooo....don't kill lag....it's the best bit about a turbo charged car....the build up, the anticipation....the not knowing what's actually going to happen every time you come on boost.. to me and I'm old now...a car that comes on boost at 2,000rpm isn't a turbo car....just doesn't work for me.
@@andrewwright. then you should just use a modern but bigger turbo like a 3076 or something so that if you ever wanted more power, you will have the possibility to. but makes no sense just to buy an olter turbo because it has more lag, just buy a bigger one haha :D
@@andrewwright. especially because running a gt28 at 350 whp versus a 3076, the 3076 is going to be much more efficient, taking less boost to do so, having less backpressure and therefore lower EGT and IATs So win win. only thing would be the cost for going from a GT to a GTX Though i would recommend going for a pulsar variant anyway so you can get a new G series for the same price as you would an old Garrett GT
Hi, my supplier told me right now about this turbo gbc20-300 over 2554r. It seems that gbc20-300 is better, tell me if there we need that restrictor? I have 1.6 270 at the wheels, is crazy because the road bearings can not hold it neither the 5 speed gearbox🥴 Awesome video🤌🏼
